Vitamin E Supplementation

Objective: Both Vitamin C and Vitamin E supplementation were associated with reduction in blood pressure (BP) in observational studies, although, results of clinical trials are inconsistent. The objective of our study is to conduct a clinical trial to observe the effects of oral supplementation of Vitamin C and Vitamin E on BP. Methods: About 60 non-teaching staffs of our college with systolic BP more than 130 mmHg and diastolic BP more than 90 mmHg were taken as subjects and divided into two groups. Initial BP and BP after oral Vitamin C, 500 mg/day for a period of 12weeks to Group 1 and initial BP and BP after oral Vitamin E, 200 IU/day, for a period of 12 weeks to Group 2 were recorded. Results: Statistical analysis was done by paired t-test, analysis of variance (ANOVA), and least significant difference (LSD) tests. *p<0.05 was considered statistically significant. Systolic 2 and diastolic 2 – after 3 months of supplementation showed 0.161 and 0.161 which is not significant. ANOVA and LSD tests show no significant results. Conclusion: Long-term trials on the effects of Vitamin C and Vitamin E supplementation on BP and clinical events are needed.

Vitamin E Supplementation

To evaluate the efficacy of four early intramuscular injections of vitamin E given in addition to continuous minimal oral vitamin E supplementation, 168 very low-birth-weight infants (≤1,500 g) have enrolled in a randomized, double-masked, clinical study. All infants received vitamin E orally, 100 mg/kg/d. In addition, on days 1, 2, 4, and 6, seventy-nine infants received vitamin E intramuscularly, 15, 10, 10, and 10 mg/kg, respectively. On the same days, 89 control infants received placebo intramuscular injections. Multivariate analysis of the 135 infants who survived ≥10 weeks showed no significant difference in the development of severe retrolental fibroplasia between these two supplementation schedules (P = .86). Plasma vitamin E levels never exceeded a mean of 3.3 mg/100 mL, and no toxicity was observed. Ultrastructural analyses of seven pairs of whole eye donations from infants receiving IM vitamin E demonstrated identical kinetics of gap junction formation between adjacent spindle cells as compared with 13 pairs of whole eye donations from control infants (P &gt; .3). Therefore, oral vitamin E supplementation affords retinal protection against the development of severe retrolental fibroplasia when initiated on the first day of life and maintained continuously until retinal vascularization is complete.

Vitamin E Supplementation

Serum vitamin E levels are reduced in newborn infants. It has been reported that this deficiency is responsible, in part, for the development of anemia in premature infants during the first 6 weeks of life. The efficacy of vitamin E supplementation for the prevention of anemia in premature infants has been studied in a randomized, controlled, and blinded trial. Premature infants whose birth weights were less than 1,500 g were given, by gavage, 25 IU of dl-α-tocopherol or a similar volume of the drug vehicle. Treatment was continued for the first 6 weeks of life. A total of 178 infants were studied. Vitamin E levels were significantly higher in a supplemented group by day 3 and for the remainder of the 6-week period. At 6 weeks of age, there was no significant difference between the supplemented and unsupplemented groups in hemoglobin concentration, reticulocyte and platelet counts, or erythrocyte morphology. It is concluded that there is no evidence to support a policy of administering vitamin E to premature infants to prevent the anemia of prematurity.

Introduction: Obesity creates health problems by increasing the risks of chronic diseases such as type 2 diabetes and cardiovascular disorders. Obesity leads to insulin resistance, higher blood glucose and cholesterol levels. Adipose tissues synthesize adiponectin which acts as anti-inflammatory, antidiabetic, and anti-atherogenic agent. Meanwhile, vitamin E is an antioxidant that acts as an anti-inflammation. Aim: The purpose of this study was to analyze the effects of vitamin E supplementation to metabolic markers on diet-induced obesity in mice. Materials and methods: Twenty-four mice (Mus musculus, L) aged four weeks were divided into six groups which were fed different diets and given vitamin E in different dosages or methods. The period of treatment was 18 weeks. The mice body weights were measured every week; blood sugar and cholesterol levels were measured every six weeks, and the adiponectin level measurement was done at week 18. Results: A repeated measures ANOVA showed that body weight and cholesterol level within groups were not significantly different [F(15,&nbsp;54)=1.417, 0.173 and F(10,&nbsp;36)=1.391, 0.224 respectively]. The glucose levels were found to be significantly different [F(7.646,&nbsp;27.526)=2.625, 0.030]. There was no significant difference in the adiponectin levels. Conclusions: Vitamin E supplementation could not prevent the increase of body weight, the elevation of blood sugar and cholesterol levels, and also could not increase adiponectin level.

ABSTRACT Objectives Long-term therapy with low-dose methotrexate (MTX) is widely used in treatment of rheumatic diseases, in children. The purpose of this study was to evaluate liver elasticity in patients with juvenile idiopathic arthritis (JIA) who received MTX and compare the results with control group. Methods Liver elasticity was evaluated with shear wave elastography (SWE) technique in 25 patients aged 3–17 years who were followed up with JIA and received MTX and compared with 25 healthy controls of the same age and weight. Factors that had an effect on liver elasticity were examined. Results The mean SWE value of patients was 2.64 ± 2.13 m/s and 24.10 ± 18.50 kPa, whereas 1.83 ± 0.16 m/s and 10.09 ± 1.83 kPa in control group. There was a significant difference in liver elasticity in the patient and control groups. When the patients were evaluated as Group 1 (&lt; 1000 mg) and Group 2 (≥ 1000 mg) according to the cumulative MTX dose, no significant difference was obtained. There was positive correlation between liver elasticity and weekly MTX dose and age. Conclusions Our study revealed that liver elasticity significantly decreased in patients who received MTX when compared with the control group. The elastography technique will be understood better over time and used safely in many areas.

Aspartame (ASP) is a sugar substitute. Its use rose because it has been demonstrated to have deleterious effects after being metabolized. In the presence of antioxidant vitamins C or E, the effects of ASP on reproductive hormones of adult male and female Albino Wister rats were investigated. A total of eighty male and female rats were used in this study. The rats were divided into four groups: group 1, received no treatment; group 2, received ASP at 40 mg/kg BW; group 3, received ASP at 40 mg/kg BW with vitamin C at 150 mg/kg BW; and group 4, received ASP at 40 mg/kg BW and vitamin E at 100 mg/kg BW. All treatments were given orally by gavage needle once daily for consecutive 90 days. The levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone hormone (TH) were measured after 90 days in blood plasma. In comparison with the control group, ASP treatment resulted in lower levels of E2, FSH, and LH in male and female rats. When the antioxidants vitamin C or E was given, the effects of ASP were reversed, and the levels of E2, LH, and FSH were increased. The testosterone hormone was likewise significantly increased by ASP, but testosterone hormone concentrations were decreased by vitamin C or E treatments. Long-term ASP consumption caused interfering with testicular and ovarian hormonal activity, while vitamins C and E on the other hand, overcome longstanding consumption ASP's effects.

During gestation and lactation, the experimental mice dams received one of the following treatments: (a) diet free of pesticide; (b) diet enriched with endosulfan (END); 30.0 µg kg−1; (c) diet free of pesticide + oral vitamin E (α-tocopherol; 200 mg kg−1 per mouse); and (d) diet enriched with END (30.0 µg kg−1) + oral vitamin E (200 mg kg−1 per mouse). At weaning, pups and dams were killed, and selected organs as well as blood samples were collected for analyses. Compared with the control results, END induced alteration in a number of biochemical and histopathological parameters either in the dams or their offspring. The ameliorative effect of vitamin E to superoxide dismutase based on the “ameliorative index (AI)” for mothers and pups was 0.84 and 0.72, respectively. The AI for malondialdehyde reached a maximum value of nearly equal to 1.0 for dams or pups. For butyryl cholinesterase, the AI was 0.90 and 0.94 for dams and pups, respectively. In conclusion, a dietary exposure during gestation and lactation to low dose of END caused significant changes in the mother but also in the weaned animals that had not been directly exposed to this pesticide. These biological and histological alterations could be reversed to a great extent by oral supplementation of vitamin E.

Vitamin E Supplementation

Abstract Background Chemotherapy often causes chemotherapy-induced peripheral neuropathy (CIPN), but effective prevention measures are still lacking. Whether vitamin E can prevent peripheral neurotoxicity caused by chemotherapy is inconclusive. Therefore, we collected related randomized controlled trials (RCTs) and conducted a meta-analysis to examine whether vitamin E could prevent CIPN. Methods We searched PubMed, EMBASE and the Cochrane databases in November 2019 for eligible trials. Two reviewers conducted the analysis independently when studies were homogeneous enough. Results Eight RCTs, involving 555 patients, were identified. Upon pooling these RCTs, patients who received vitamin E supplementation of 600 mg/day had a significantly lower incidence of peripheral neuropathy (RR 0.31; 95% CI 0.14 to 0.65; P = 0.002) induced by chemotherapy compared with the placebo group. Vitamin E played a key role in decreasing the incidence of peripheral neuropathy in the cisplatin chemotherapy group (RR 0.28; 95% CI 0.14 to 0.54; P = 0.0001). With regard to improvements in sural amplitude, vitamin E supplementation significantly decreased patients’ sural amplitude after three rounds of chemotherapy (RR -2.66; 95% CI -5.09 to -0.24; P =0.03) in contrast with that of placebo supplementation, while no significant difference was observed when patients were treated with vitamin E after six rounds of chemotherapy. In addition, the vitamin E group had better improvement in the neurotoxicity score (RR -2.65; 95% CI -4.01to -1.29; P = 0.0001) and a lower incidence of reflexes and distal paraesthesias (RR 0.50; 95% CI 0.29 to 0.87; P = 0.01) compared to the control group. Conclusion Available data included in this meta-analysis showed that vitamin E supplementation can confer modest improvement in the prevention of CIPN. However, large-scale, well-designed RCTs are needed to confirm the exact role of vitamin E supplementation in the prevention of CIPN.

Abstract Background Ischemic heart disease (IHD) is a major underlying etiology in patients with heart failure (HF). Although the impact of IHD on HF is evolving, there is a lack of understanding of how IHD affects long-term clinical outcomes and uncertainty about the role of IHD in determining the risk of clinical outcomes by gender. Purpose This study aims to evaluate the gender difference in impact of IHD on long-term clinical outcomes in patients with heart failure reduced ejection fraction (HFrEF). Methods Study data were obtained from the nationwide registry which is a prospective multicenter cohort and included patients who were hospitalized for HF composed of 3,200 patients. A total of 1,638 patients with HFrEF were classified into gender (women 704 and men 934). The primary outcome was all-cause death during follow-up and the composite clinical events of all-cause death and HF readmission during follow-up were also obtained. HF readmission was defined as re-hospitalization because of HF exacerbation. Results 133 women (18.9%) were died and 168 men (18.0%) were died during follow-up (median 489 days; inter-quartile range, 162–947 days). As underlying cause of HF, IHD did not show significant difference between genders. Women with HFrEF combined with IHD had significantly lower cumulative survival rate than women without IHD at long-term follow-up (74.8% vs. 84.9%, Log Rank p=0.001, Figure 1). However, men with HFrEF combined with IHD had no significant difference in survival rate compared with men without IHD (79.3% vs. 83.8%, Log Rank p=0.067). After adjustment for confounding factors, Cox regression analysis showed that IHD had a 1.43-fold increased risk for all-cause mortality independently only in women. (odds ratio 1.43, 95% confidence interval 1.058–1.929, p=0.020). On the contrary to the death-free survival rates, there were significant differences in composite clinical events-free survival rates between patients with HFrEF combined with IHD and HFrEF without IHD in both genders. Figure 1 Conclusions IHD as predisposing cause of HF was an important risk factor for long-term mortality in women with HFrEF. Clinician need to aware of gender-based characteristics in patients with HF and should manage and monitor them appropriately and gender-specifically. Women with HF caused by IHD also should be treated more meticulously to avoid a poor prognosis. Acknowledgement/Funding None
